As you said, all day long, we've heard from republican fire brands as well as democrats grappling with what the governor said about 47% of potential voters. Abc's jake tapper and jon karl bring us two perspective on this seismic day. Jon karl, we begin with you, tell us about the republican reaction, what the government said about all of those voters. And, diane, there's also the 47%. Who are those people. You know, for the most part, these are people with jobs. More than half of them work, but they make less than $50,000 a year. About a quarter of them are senior citizens who just don't pay taxes on their social security benefits. Diane, only 15% of those who don't pay federal income tax are people who don't work and are welfare unemployment. The kicker, diane, is that romney may have insulted some of his own voters. If you look at the last few presidential elections, nearly half of those who paid little or no income tax actually voted republican. As for the conservative reaction. Conservatives deeply divided. Some actually liking what romney had to say. Listen to rush limbaugh today. This is, to me, such an opportunity to espouse conservatism and to explain -- and we know romney's got it in him, because what he said to these people. But bill crystal, who is a highly influence commentator today called romney's words stupid and arrogant. So republicans divided tonight.

And -- that's going to be the tone from the president that he is the country. Which is what those persuadable voters want. Expect a tough commercial very soon from the obama campaign. We remember four years ago the president was at a fund-raiser during the primary, but he too was caught on tape. He was talking about the difficulty of reaching smalltown pennsylvanian, they get bitter, cling to religion and guns and xenophobia. Here's the difference between what they said. What obama said then was seven months before the election. He had time to change people's views. This was seven weeks and mitt romney does not have time to squander, diane. 49 days.
